基于动态综合评价的无线传感器网络数据转发算法

Data Forwarding Algorithm Based on Dynamic Comprehensive Evaluation in Wireless Sensor Networks

为了延长无线传感器网络的生存周期,必须在传感数据转发过程中尽量均衡节点能耗。利用动态综合评价有效转发节点的多属性信息来进行下一跳节点的选择,通过最优邻居节点转发传感数据可以达到网络数据流量分配合理和能耗均衡的目标。仿真实验表明,提出的算法较同类算法在均衡节点能耗和延长网络生存周期方面具有一定的优势。

In order to prolong the lifetime of wireless sensor networks,the energy consumption of sensor nodes in the process of sensing data forwarding must be balanced.In this paper,we use the dynamic comprehensive evaluation method to evaluate those multi-attribute information of effective forwarding nodes for the choice of the next-hop node.Through the optimal neighbor node,the sensor data forwarding scheme can achieve reasonable data flow distribution and balanced energy consumption.Simulation results show that the proposed algorithm has certain advantages over those similar algorithms in terms of balancing energy consumption and prolonging the network lifetime.
